I see a similar problem using e.g. the following .gitignore to exclude
everything except C source files and header files:

    *
    !*/
    !*.c
    !*.h

In Git 1.8.3 'git status' will show other files as untracked while in
Git 1.8.2.3 I don't have that problem. I bisected to find that the
offending commit is v1.8.2.1-402-g95c6f27. 

I am not on OSX, however, but on Linux (Ubuntu 12.04 and RHEL 5.8) so
this may be a separate issue. I've also gotten the impression that this
is intentional. In any case I cannot create a .gitignore that achieves
the same for both older and newer versions of Git.
